in quite the same manner. The enzyme-solution thus prepared, 

 served for the following experiments. 



The first experiment .was made to ascertain the influence 

 of the reaction on the behavior of the enzymes. The materials 

 tested with the addition of some thymol at room-temperature, 

 or at 36 0 C, were sharply cut slices of coagulated egg-albumen, 

 fibrin and starch-solution. 



The results were as follows : —
